Alright, let's solve this math problem step by step. First, we have the number 538. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 7. So, we're going to take the number 538 and add it to itself 7 times.
Step 1: 0 + 538 = 538
Step 2: 538 + 538 = 1076
Step 3: 1076 + 538 = 1614
Step 4: 1614 + 538 = 2152
Step 5: 2152 + 538 = 2690
Step 6: 2690 + 538 = 3228
Step 7: 3228 + 538 = 3766

So, 538*7 = 3766
